Uncompromising, reliable, and impressively lightweight, its a do-it-all shell that adapts to any day on the trail with dark skies overhead.Our VerdictThe Rab Downpour Trail Light 2.5L Jacket weighs just 202g (UK12) and feels purpose-built for trail running or minimalist mountain days. The Pertex Shield fabric handles wind and persistent rain well, offering decent breathability for a 2.5-layer shell. I liked the simplicity, a single chest pocket, a clean hem drawcord, and low-profile cuffs. That said, I preferred hook-and-loop closures over the extended elastic cuffs for better adjustability, especially in cold or wet transitions. The hem at the front sits noticeably high (in size large, it sits above the belt line), which may not suit everyone for pack coverage or layering.Ideal for lightweight trail missions where reliable protection and a streamlined design take priority.- Reviewed by Ultralight Outdoor GearFeaturesSemi-elasticated hood with stiffened peak and rear volume adjustment for enhanced fitYKK AquaGuard centre front zip with chin guard for comfortYKK zipped chest pocket doubles as integrated stuff sackSemi-elasticated extended cuffs for comfortSingle side rear hem adjustment with anti snag tetherReflective Rab logo and rear printSpecificationsUK 8 weighs: 186gUK 10 weighs: 197gUK 12 weighs: 202gUK 14 weighs: 219gCentre back length(Size10): 65cm/25.5inFit: SlimMaterial & Construction20D Pertex Shield 2.5-Layer construction waterproof technology with fluorocarbon-free DWR (85gsm) HH: 20,000mm/MVTR: 20,000 g/m2/24hrs55% Polyamide, 45% Polyamide (Recycled) with Polyurethane membraneHelp & advice:Pertex Shield Technology ExplainedTime-Saver Guide to Choosing a Waterproof JacketTime-Saver Guide to PFC FreeAbout RabMVTR BreathabilityHydrostatic HeadRab Sustainability and Responsibility
